Also, is this getting political, in this game? The game was created when this name change did not yet exist. But one thing I have to say: That this was not adapted has nothing to do with the current political events.
But I can well imagine that only the game developers can make such a change and not the Sokkeradmins. Unfortunately, the game developers are no longer active here.
Name should be in the country's official language, yet transliterated to roman characters, so I guess it would be 'Severna Makedonija' (to confirm anyway, as cyrilic is not my forte).
DEVs, and perhaps high level admins, are the nly ones who could make the change, yet probably the approval from the formers might be needed for the change to take place. If some day the want, they will end eventually changing it, but until then... this is Sokker, so patience :)
